基于Creator和Vega的红外/SAR成像仿真

在此使用Creator软件建立了带纹理的目标三维模型,以及利用Vega的TMM和MAT工具分别对目标纹理和大气环境进行了建模。基于Vega及其扩展模块远红外传感器仿真模块对红外图像进行了仿真;基于Vega及其扩展模块雷达仿真模块对SAR成像进行了仿真。针对同一场景、同一目标的红外/SAR图像融合过程中存在的图像获取问题,提出一种对同一探测目标的半真实半仿真图像获取方法;使用传感器视效模拟模块进行同一时刻、场景和大气条件下的SAR图像和红外图像仿真。使用Cretor和Vega软件生成红外/SAR图像具有周期短、实时性高的特点,可以很好地解决红外/SAR图像获取难的问题,在军事与民用领域中均有广泛的应用。

IR/SAR iimaging simulation based on Creator and Vega

A three-dimensional target model with texture was built with Creator software. The models of the target texture and atmospheric environment were established by means of TMM and MAT tools in Vega. The infrared image is simulated on the basis of Vega and its expansion module（far-infrared sensor simulation module）. The SAR imaging is simulated on the basis of Vega and its expansion module （radar simulation module）. In order to solve the problem existing in the same scene and same target infrared image/SAR image fusion,a acquisition method of the half-real half-simulication image of same target is proposed. The sensor simulication visual module is used to simulate the SAR image and IR image in the same time,scene and atmospheric condition. Using Creator and Vega softwares to generate infrared/SAR images has the characteristics of short cycle and high real-time features,which can solve the problem of IR/SAR image acquisition. It has been widely used in military and civil fields.
